Ok so, here goes.
The truck is a 1992 4.3 V6 with a 5 speed manual. The exhaust that came with it when I bought it is as follows :
Stock manifolds
Stock Y pipe
Stock ancient catalytic converter ( semi plugged up, can tell after an hour of highway driving )
From the cat, it branches to another Y with glasspacks ( brand unknown , but look like 24' long, )
Pipe
12" long 3" outside diameter tips.
I am seriously considering a cat delete, with a straight pipe welded in its place. A shadetree mechanic friend of mine told me to just ram a pipe through the cat, but I know that an expansion chamber is NOT good for a V6, s I'm hesitant to go that route. Also, I'm pretty sure that I'll never get those bolts off and that cat will have to come off with a Sawzall, so I might as well do the pipe, anyhow.
My question is this : I'm pretty sure that the downpipe is a 3' pipe, do I want to make the cat delete pipe 3', or should I reduce it because of the 262 V6's sensitivity to backpressure ? I know that they're more tempermental than a 350 V8 that way. . . .
What are the board's thoughts on this ?
Also, replacement cat is NOT an option; I am aware of the legal and environmental ramifications of a cat delete, etc.
